Lancaster, CA Building Setbacks & Zoning: Structure Height Limits (2026)

060 of Title 17 sets separate development-standards tables for each residential lot type in Lancaster. 5 zone (minimum 100,000-square-foot lots) and the RR-1 zone (minimum 40,000-square-foot lots) both allow structures up to 40 feet, while the semi-rural residential SRR zone (minimum 20,000-square-foot lots) caps height at 35 feet. On a standard single-family or duplex lot, the R-15,000, R-10,000, R-7,000 and SFR corner-duplex designations all share the same 35-foot ceiling, alongside a maximum lot coverage that ranges from 40 percent on R-15,000 and R-10,000 lots up to 50 percent on R-7,000 lots and 45 percent on SFR corner lots.

' The Building and Safety Division measures height as part of plan check for any new single-family home, duplex, or small apartment/condominium building of 3 to 15 units, which follows its own MDR/HDR standards table within the same section. 41, Article IV is deemed to satisfy these height and massing requirements without a separate discretionary finding. Because the limit is tied to zone and lot type rather than a single citywide number, property owners should confirm their parcel's zoning designation before finalizing architectural plans, since a home designed to the RR-1 40-foot standard would be rejected outright if the parcel is actually zoned SRR or R-7,000.
